Meta-Analysis Review
Despite the widely held belief that men are more narcissistic than women, there has been no systematic review to establish the magnitude, variability across measures and settings, and stability over time of this gender difference. Drawing on the biosocial approach to social role theory, a meta-analysis performed for Study 1 found that men tended to be more narcissistic than women (d = .26; k = 355 studies; N = 470,846). This gender difference remained stable in U.S. college student cohorts over time (from 1990 to 2013) and across different age groups. Study 1 also investigated gender differences in three facets of the Narcissistic Personality Inventory (NPI) to reveal that the narcissism gender difference is driven by the Exploitative/Entitlement facet (d = .29; k = 44 studies; N = 44,108) and Leadership/Authority facet (d = .20; k = 40 studies; N = 44,739); whereas the gender difference in Grandiose/Exhibitionism (d = .04; k = 39 studies; N = 42,460) was much smaller. We further investigated a less-studied form of narcissism called vulnerable narcissism-which is marked by low self-esteem, neuroticism, and introversion-to find that (in contrast to the more commonly studied form of narcissism found in the DSM and the NPI) men and women did not differ on vulnerable narcissism (d = -.04; k = 42 studies; N = 46,735). Study 2 used item response theory to rule out the possibility that measurement bias accounts for observed gender differences in the three facets of the NPI (N = 19,001). Results revealed that observed gender differences were not explained by measurement bias and thus can be interpreted as true sex differences. Discussion focuses on the implications for the biosocial construction model of gender differences, for the etiology of narcissism, for clinical applications, and for the role of narcissism in helping to explain gender differences in leadership and aggressive behavior. Readers are warned against overapplying small effect sizes to perpetuate gender stereotypes.

Meta-Analysis Review
Eating disorders are widespread illnesses with significant impact. There is growing concern about how those at risk of eating disorders overuse online resources to their detriment. We conducted a pre-registered systematic review and meta-analysis of studies examining Problematic Usage of the Internet (PUI) and eating disorder and related psychopathology. The meta-analysis comprised n = 32,295 participants, in which PUI was correlated with significant eating disorder general psychopathology Pearson r = 0.22 (s.e. = 0.04, p < 0.001), body dissatisfaction r = 0.16 (s.e. = 0.02, p < 0.001), drive-for-thinness r = 0.16 (s.e. = 0.04, p < 0.001) and dietary restraint r = 0.18 (s.e. = 0.03). Effects were not moderated by gender, PUI facet or study quality. Results are in support of PUI impacting on eating disorder symptoms; males may be equally vulnerable to these potential effects. Prospective and experimental studies in the field suggest that small but significant effects exist and may have accumulative influence over time and across all age groups. Those findings are important to expand our understanding of PUI as a multifaceted concept and its impact on multiple levels of ascertainment of eating disorder and related psychopathology.

Review
Body dissatisfaction plays a prominent role in gender dysphoria. In some individuals body dissatisfaction appears to manifest disordered eating in order to suppress bodily features of natal gender and accentuate features of gender identity. To date, there has been no systematic review of the literature pertaining to body dissatisfaction and disordered eating in trans individuals. Such a review may highlight important implications for clinicians working with trans people. Therefore, the aim was to critically and systematically review the available literature examining body dissatisfaction or disordered eating in a trans population, and also the literature pertaining to how body dissatisfaction and disordered eating are related in trans people. This review found three studies that explored disordered eating in trans people, five studies that explored body image and disordered eating in trans people, and 18 studies that explored body image in trans people. The findings from this review suggest that body dissatisfaction is core to the distress trans people experience and that this dissatisfaction may also put some individuals at risk of developing disordered eating. Additionally, the findings appear to suggest that gender dysphoria treatment is successful at increasing body satisfaction and improving body image. The clinical implications are discussed.

A Systematic Review of Gender-Based Violence Prevention and Response Interventions for HIV Key Populations: Female Sex Workers, Men Who Have Sex With Men, and People Who Inject Drugs.
Gender-based violence (GBV) is that perpetrated based on sex, gender identity, or perceived adherence to socially defined gender norms. This human rights violation is disproportionately experienced by HIV key populations including female sex workers (FSW), people who inject drugs (PWID), and men who have sex with men (MSM). Consequently, addressing GBV is a global priority in HIV response. There is limited consensus about optimal interventions and little known about effectiveness. Our systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and was registered in International Prospective Register of Systematic Reviews. Peer-reviewed and non-peer-reviewed literature were searched for articles that described a GBV prevention or response intervention specifically for key populations including FSW, PWID, and MSM. Results were organized by level(s) of implementation and pillars of a comprehensive GBV response: prevention, survivor support, and accountability/justice. Of 4,287 articles following removal of duplicates, 32 unique interventions (21 FSW, seven PWID, and nine MSM, not mutually exclusive) met inclusion criteria, representing 13 countries. Multisectoral interventions blended empowerment, advocacy, and crisis response with reductions in violence. Individual-level interventions included violence screening and response services. Violence-related safety promotion and risk reduction counseling within HIV risk reduction programming reduced violence. Quantitative evaluations were limited. Violence prevention and response interventions for FSW, PWID, and MSM span individual, community, and multisectoral levels with evidence of promising practices at each level. The strongest evidence supported addressing violence in the context of sexually transmitted infection/HIV risk reduction. As interventions continue to emerge, the rigor of accompanying evaluations must simultaneously advance to enable clarity on the health and safety impact of GBV prevention and response programming.

Review
Sexual orientation and gender identity (SOGI)-diverse populations experience discrimination in organ and tissue donation and transplantation (OTDT) systems globally. We assembled a multidisciplinary group of clinical experts as well as SOGI-diverse patient and public partners and conducted a scoping review including citations on the experiences of SOGI-diverse persons in OTDT systems globally to identify and explore the inequities that exist with regards to living and deceased OTDT. Using scoping review methods, we conducted a systematic literature search of relevant electronic databases from 1970 to 2021 including a grey literature search. We identified and screened 2402 references and included 87 unique publications. Two researchers independently coded data in included publications in duplicate. We conducted a best-fit framework synthesis paired with an inductive thematic analysis to identify synthesized benefits, harms, inequities, justification of inequities, recommendations to mitigate inequities, laws and regulations, as well as knowledge and implementation gaps regarding SOGI-diverse identities in OTDT systems. We identified numerous harms and inequities for SOGI-diverse populations in OTDT systems. There were no published benefits of SOGI-diverse identities in OTDT systems. We summarized recommendations for the promotion of equity for SOGI-diverse populations and identified gaps that can serve as targets for action moving forward.

BACKGROUND
Vaginoplasty is a gender-affirming procedure for transgender and gender diverse (TGD) patients who experience gender incongruence. This procedure reduces mental health concerns and enhances patients' quality of life. A systematic review investigating the sexual health outcomes of vaginoplasty has not been performed.
OBJECTIVES
To investigate sexual health after gender-affirming vaginoplasty for TGD patients.
DATA SOURCES
MEDLINE/PubMed, Embase, Scopus, and PsycINFO databases were searched, unrestricted by dates or study design.
METHODS
We included primary literature that incorporated TGD patients, reported sexual health outcomes after vaginoplasty intervention and were available in English. Outcomes included at least one of these sexual health parameters: sexual desire, arousal, sensation, activity, secretions, satisfaction, pleasure, orgasm, interferences, or aids.
RESULTS
Our search yielded 140 studies with 12 different vaginoplasty surgical techniques and 6,953 patients. The majority of these studies were cross-section or retrospective cohort observational studies (66%). 17.4%-100% (median 79.7%) of patients (n = 2,384) were able to orgasm postoperatively regardless of revision or primary vaginoplasty techniques. Female Sexual Function Index was the most used standardized questionnaire (17 studies, ranging from 16.9 to 28.6). 64%-98% (median 81%) of patients were satisfied with their general sexual satisfaction. The most common interference of sexual activity was dyspareunia.
CONCLUSIONS
The heterogenous methods of measuring sexual outcomes reflect the difficulty in comparing single-center surgical outcomes, encouraging the need for a standardized and validated metric for reporting sexual health after vaginoplasty for TGD patients. The most common sexual health parameter reported is sexual activity while therapeutic aids and pleasure were the least reported parameters. Future studies are needed to improve and expand methods of measuring sexual health, including prospective studies, validated questionnaires, and inclusive metrics. Systematic review registration number: PROSPERO 01/01/2021: CRD42021224014.

Nicotine & Tobacco Research : Official... Mar 2022ransgender and gender diverse (TGD) people have a higher prevalence of tobacco and nicotine use compared to their cisgender peers.
INTRODUCTION
ransgender and gender diverse (TGD) people have a higher prevalence of tobacco and nicotine use compared to their cisgender peers.
AIMS AND METHODS
Using the minority stress model as a guide, we conducted a systematic review of correlates of tobacco and nicotine use among TGD people. We reviewed the literature from Pubmed, PsycINFO, and CINAHL between April 1, 1995 and April 20, 2021. Article inclusion criteria were the following: written in English, reported empirical data, sampled exclusively or reported separate outcomes for transgender/gender diverse people, and reported correlates of tobacco or nicotine use, broadly defined. The first and second authors reviewed the articles retrieved from the search and from gray literature (relevant listserv solicitations) for inclusion. They then reviewed references of any included articles for additional candidate articles.Results: This resulted in 35 articles for review, which were synthesized in a qualitative fashion. The overall quality of the articles was fair, with the articles ranging from poor to fair quality and using primarily cross-sectional design and survey methods.
CONCLUSIONS
Overall, the literature demonstrated external minority stressors were mostly researched (and supported) correlates of tobacco and nicotine use among TGD people. There is a critical need for higher quality research, such as longitudinal or experimental designs, to improve our understanding and prevention of tobacco and nicotine use in this population.
IMPLICATIONS
This systematic review used the minority stress model as a guide to understand correlates of tobacco and nicotine use among transgender and gender diverse people. Literature of fair quality demonstrated that external minority stressors were the most researched and supported correlates of tobacco and nicotine use within the framework of the minority stress model. This review demonstrated a critical need for higher quality research, such as longitudinal or experimental designs, to improve our understanding and prevention of tobacco and nicotine use in this population. Preliminary findings from the limited literature highlight factors that may be relevant to target with this population, including general/environmental stressors and external minority stressors such as discrimination.

Review
The preponderance of HIV interventions have been behavioral, targeting individual, dyadic, or group dynamics. However, structural-level interventions are required to decrease HIV transmission and increase engagement in care, especially for men who have sex with men (MSM), particularly Black and Latinx MSM. A systematic literature review was conducted to assess the current state of structural interventions; only two studies detailing structural interventions related to HIV for Black and Latinx MSM in the US were identified. An additional 91 studies which discussed structural-level barriers to optimal HIV outcomes among MSM, yet which did not directly evaluate a structural intervention, were also identified. While this paucity of findings was discouraging, it was not unexpected. Results of the systematic review were used to inform guidelines for the implementation and evaluation of structural interventions to address HIV among MSM in the U.S. These include deploying specific interventions for multiply marginalized individuals, prioritizing the deconstruction of structural stigma, and expanding the capacity of researchers to evaluate "natural" policy-level structural interventions through a standardization of methods for rapid evaluative response, and through universal application of sex, sexual orientation, and gender identity demographic measures.

Review
OBJECTIVE
The current study examined the frequency with which randomized controlled trials (RCTs) of behavioral and psychological interventions for anxiety and depression include data pertaining to participant sexual orientation and nonbinary gender identities.
METHOD
Using systematic review methodology, the databases PubMed and PsycINFO were searched to identify RCTs published in 2004, 2009, and 2014. Random selections of 400 articles per database per year (2,400 articles in total) were considered for inclusion in the review. Articles meeting inclusion criteria were read and coded by the research team to identify whether the trial reported data pertaining to participant sexual orientation and nonbinary gender identities. Additional trial characteristics were also identified and indexed in our database (e.g., sample size, funding source).
RESULTS
Of the 232 articles meeting inclusion criteria, only 1 reported participants' sexual orientation, and zero articles included nonbinary gender identities. A total of 52,769 participants were represented in the trials, 93 of which were conducted in the United States, and 43 acknowledged the National Institutes of Health as a source of funding.
CONCLUSIONS
Despite known mental health disparities on the basis of sexual orientation and nonbinary gender identification, researchers evaluating interventions for anxiety and depression are not reporting on these important demographic characteristics. Reporting practices must change to ensure that our interventions generalize to lesbian, gay, bisexual, and transgender persons. (PsycINFO Database Record

Review
BACKGROUND
Health inequities have been shown to have negative effects on patient care and the healthcare system. It is important for orthopaedic trauma surgeons and researchers to understand the extent to which patients are affected by these inequities.
METHODS
We conducted a scoping review as outlined by the Joanna Briggs Institute and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. We searched PubMed and Ovid Embase for articles relating to orthopaedic trauma surgery and health inequities.
RESULTS
After exclusion criteria were applied, our final sample consisted of 52 studies. The most frequently evaluated inequities were sex (43 of 52 [82.7]), race/ethnicity (23 of 52 [44.2]), and income status (17 of 52 [32.7]). The least frequently evaluated inequities were lesbian, gay, bisexual, transgender, and queer identity (0 of 52 [0.0]) and occupational status (8 of 52 [15.4]). Other inequities evaluated included rural/underresourced (11 of 52 [21.1]) and educational level (10 of 52 [19.2]). No trend was observed when examining inequities reported by year.
CONCLUSION
Health inequities exist in orthopaedic trauma literature. Our study highlights multiple inequities in the field that need further investigation. Understanding current inequities and how to best mitigate them could improve patient care and outcomes in orthopaedic trauma surgery.
